L. P. HALLADAY AUTOMOBILE BUMPER Filed Feb, 21, 1924 2 sheets-sheet 2 AUTOMOBILE 'LE-BUMPER.

To @YZ whirl/152i may concern r Be it known that L Lewis P. ALLADAY, :i citi/:en of the United States, residing et Decatur. in the countyy ot Macon and Siete of ilinois, have, invented e cci-tuin new and usefu improvement inf'iuternobile Bump! i-rs, ot' wi 'ch the folowing tion,

My invention relates izo' improvements in automobile bumpers and pnrticnmly to the clump assemofy whereby the seguente bumper ber eiements ene heid in 'rigid essernbled nonaidjustzrbla ti'aongb demountebie relation. It bas for one object. to provide a new and 'improved forni of clamp as" semhly by which the bars may be rigidly., though denlonnteby 'fastened together and by which the same clamp assembly may be used to assist in attaching tbe impact bar to :in entn'nnobie frame or other sntebie supporting eei'nent. @their objects: Witt appear 'from time to time in. the spr'eciicei'ion mit claims,

My invention iustreted moreel lese diegrunnnntically in the accompanying drawings, Wberein- Figure l is e front elevation;

Figure 2 is e plan .f'iew;

Figure 3 is a section dong the line 33 of Figure l:

Figline L is u section along the line 1f-4 (3f-Figure 3:,

Figures G anni T are [retail views ot modified forms.

Like parte :1re indicated by like chemo is e specifica-- iere throughout the speci-.ficet/ion und drewings.

A, A1 are parallel upper und ,lower 'iet strip impact bars. They muy be mede of spring steel und may be inished et, their ends in any suitable manner. They ex tend nornmly clear across the' front of the niotor vehicle. The upper and lower opposed edges of the bare A, A1 are notched in opposition :it A2 und A3. These notches are cut in the metal und formed before the assembly takes place.

B, i' are front chimp members overlying tbe .front impact feces of the bers end han ing reerverdy und -upnf'ardly and downn'nrdiy bent ends B17 B2, iese booke engagging the upper and lower edges respeciveiy of the impact, bars. i3 is e bolt heving e` round bead lo engage the frontfece .rear ciznnp 'member having;

.chimp T adapted to contain e nut E which when screwed home on the bolt bf eempe the two impact bers together. between the two damp members and is emtirey con tained Within the recess so es to lean/e e tiered uninterrupted Surface at, thebeck of the rear clamp. B12, B12 are ribs en the beck of the clamp prog'ectingf rearwardly te form e. channel ade-pied to engage en@ position e. holding or reinforeing bnr B13. n, the preferred form, 'this ber E extends across the beck of tbe imnnp.1 emi inn Wurdly and nwardly Curved ende B engagging tiie'cbannel formed between the ribs on the beck cexnp. The ends of "this ber ere perforated as at B15 to engage the bolt E and the nut, B1 ie provided to ioek the parte together. y n' It wii be noted that, the fact that the ends of the reenit'orcing bei are epetured to eng-gre the bolt and the 'further inet that tbe impact bers ere notched to higs in the clamps. prevents any displacement or movement of the bumper parts after they nre once assembled :and perticuery prevents :any relative movement et the two impact members with respect te one another orwith respect to .the reenforcing or ioding' ber.

In the modified form shown in Fgnre 5,

vthe back clamp member has ne recess and the nut B engages the beck of the cazfnp. An in'evrgrel lng; C projects rezritvardy. from the hemp and may be belted or riveted to the forward end C1 of the crosse ber 'n Figure 6, the lug); Ci" is subetituteib This cxtencs clear back so that, the rear bere C* is straightwithont the torwercr beni'. extension und nifty be bote er riveted to the tug U3.

- invention..

which the clamp B5 is mounted, projects forward direct from the automobile trame.

lt will be evident that while I have shown in my drawings,`an operative device, still many changes might be made in the-size, shape and disposition of parts without departing, materially from the spirit of my l wish, therefore, that my show* ing be taken in a large sense as diagram'- matic.
